Research

My current research interests span the fields of DATABASES and DATA MINING. In particular, I am interested in efficient query processing techniques in database systems (multidimensional data management, spatio-temporal data management), algorithms for mining massive graphs (dense subgraph discovery, frequent subgraphs, hidden graphs, probabilistic graphs), parallel and distributed techniques for massive data sets (MapReduce, Pregel) and data management and mining over data streams.
